SASH-OPERATING- DEVICE.

Application filed January 18, 1916. Serial No. 72,870.

To all whom it may concern:

Be it known that we, WILLIAM C. LEA and JOSEPH C. GEORGE, both citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Sash-Gperating Device, of which the following is a specification.

Our invention relates to windows, and more particularly to casement windows, but is applicable to any form of window or transom which is hinged along one edge to swing either in or out.

The principal object of our invention is to provide a sash operating device for such a window of simple form and construction.

One of the principal objections to casement windows is the diihculty of operating them where curtains or screens are used, particularly in the latter case. In the form shown, in which the invention is applied to a casement window which swings outwardly, it is necessary to place the screen inside, thereby shutting off access to the window proper without disa'rranging the window shade, curtains and opening the screen.

A further object of our invention is to provide an operating device by means of which a window of the character described placed on the outside of the opening may be opened or closed without disarranging the shade or curtains, and without opening the screen. That is, the window is entirely operated in so far as opening or closing is concerned from the inside of the room.

A further object is to provide a sash operating device of the character described which imparts the maximum range of movement to the sash so that the same may be swung at right angles to the sash when in closed position thereby giving a full w'n dow opening.

A further objection of casement windows lies in the diflicultv of gaining-access to the outer side for cleaning purposes, and it is a further object of our invention to provide a casement window in. which the sash can be so turned that access is had to both sides thereof.

A further object of our invention is to provide a sash operating device having the above characteristics which will have a few parts, and which will be ornamental in 0ppearance, and take up comparatively little space in its installation.

Further objects and advantages will be made evident hereinafter.

In the drawings which are for illustrative purposes only: Figure 1 is an elevation of casement window equipped with our invention. Fig. 2 is a similar view on a larger scale, a portion of the window being broken away and shown in section to better illustrate our invention. Fig. 3 is a plan view shown in section on a plane represented by the line w w of Fig. 1 looking in the direction of the arrows, various positions of the sash being shown in dotted or broken lines to better illustrate the various positions of the window. Fig. 4- is a section on a plane represented by the line nc*m* of Fig. 3, this plane being viewed in the direction of the arrows. Fig. 5 is a perspective view of the various parts of the mechanism slightlv separated to better show their relation, and Fig. 6 is a plan view showing the sector and latch, this plan be ing viewed from below. Fig. 7 is a plan view of the swinging arm at the pivot thereof taken from above.

In these drawings a sash 11 is provided, this sash fitting inside a casement 12, the easement being formed of a top member 13, side members 14. and a bottom member 15. A window sill 16 is located inside the easement at the lower end thereof, this window sill beingattached to a spacer 17 and to an apron 18, the parts 12 to 18 inclusive being secured together to form a 7 permanent stationary structure. Inside the window may be placed a screen 20, this screen being secured inside vertical straps 20 which are secured to the inside of the members 14. forming a unitary structure therewith, or the screen may be hinged at one side thereof and adapted to swing in wardly into the room, such construction be ing common and well known.

Secured to the top and bottom of the sash 11 are sash pivot plates 21, these sash pivot plates having a cylindrical portion 22 which is set into the sash, and a flat portion 23 whichis secured to the sash through holes 24 by screws 25. Brace pivot plates 26 are secured by means of screws 27 to the top and bottom of the sash, the brace pivot plates having holes 28 therein. The sash pivot plates 21 are provided with an opening 30 in which a slide pivot pin 31 turns freely. The slide pivot pin 31 is secured to a slide 32, the slide 32 sliding treely inside in a sheet metal guide 33, the guide 33 being in box form as shown in Fig. 4. The guide 33 is at the bottom ofthe easement 12. The slide 32 is restrained from sliding in the guide by means of a flat spring 35, this spring being secured to the slide 32 by means of rivets 36. A catch pin 37 is secured in the flat spring 35 and projects through the slide 32 dropping into a small hole 38 formed in the guide 33 in such a position as to hold the slide 32 at its extreme left hand position as shown in the drawings.

A swinging arm 40 is provided in the bot tom of the window, this arm consisting of a brace portion 41 and an operating portion 42. A swinging arm 43 is also provided in the top of the window, the swinging arm 43 being similar to the swinging arm 40 with the omission of the operating portion 42. The portions 41 and 42 of the arm 40 are connected by means of a box 45, this box being of suiiicient size to allow the end of the slide to fit therein, and having a lower portion 46 adapted to extend under the bottom of the slide when it is in its normal position therein. A locking slot 47 is provided in the top of the box 45 into which the slide pivot pin 31 fits and slides.

A casement pivot plate 50 is rigidly secured to the casement by means of screws 51, this casement pivot plate carrying a casement pivot pin 52, this casement pivot pin 52 extending up and engaging an opening 53 in the lower portion 46 of the box 45, so that the swinging arm is restrained to turn about the pin 52 which is rigidly secured in the casement by means of the casement pivot plate 50.

On the outer end of the brace portion 41 of the swinging arm 40 is located a brace pivot pin 60, this pin passing through the hole 28 in the brace pivot plate 26, and having an enlarged head 61 so that it is retained in the hole 28 turning freely therein. On the outer end of the operating portion 42 of the swinging arm 40, which swings in anopening below the window sill 16, is located a latch 65, this latch consisting of a fiat piece of steel. bent at right angles as best shown in Fig. 5, and having a. large end 66. The latch 65 is provided with an l. shaped slot 67, this slot sliding on pins 68 secured in the operating portion 42 of the arm 40. A spring 69 engages small projections formed on the latch 65, and on a bent end 70 which is formed on the operating portion 42 of the swinging arm 40. The end 66 of the latch 65 is of such a shape, and is so located that it engages a plurality of notches 71 these notches being formed in a sector 72 secured below the window sill 16 in such a position as to be out of sight and fully protected by the window sill 16. The upper swinging arm 43 is provided with its equivalent structure to the lower swinging arm 41, with the exception of the part 42, and. the parts 66 to 72 inclusive.

The method of operation is as follows: When used to open and close the window the slide pivot pin 31, and the easement pivot pin 52 are in line as shown in Fig. 3, the slide 32 being restrained in this position by the catch pin 37, and the window being swung open or closed by means of the operating portion 42, the window being locked in any position by means of the end 66 of the latch 65 which engages the notches 71 in the sector 72. This latch 65 can be disengaged from the sector 72 by a pressure of the fingers against the spring 69, and if desired the latch 65 can be locked in its disengaged position by moving it sidewise into the dotted position shown at A in Fig. 6, so that the window can be opened or closed, or moved to any of its positions as hereinafter explained without having to pay any particular attention to thelatch 65. In the ordinary opening and closing of the window itmoves from its closed position into its open position as shown at B in Fig. 3 simply by turning the window by means of the operating portion 42 of the swinging arm 40, the swinging arm 43 moving in synchronism therewith. It will be noted that the operating portion 42 6X- tends into the room under the window sill 16, thus allowing the window to be operated without interfering with the screen 20, or with any shades or curtains which may be hanging inside the window, this being the ordinary operation thereof. It will further be noted that the window may be locked in its open or closed position by means of the sector 72.

When it is desired to clean the window, the window is opened to its full position as shown. at B in Fig. 3, the screen 20 being also opened. Theend of the fiat spring 35 is then raised lifting the catch pin 37 out of the hole in the guide 33, this allowing the slide 32 to be moved to the right in the guide 33. No spring corresponding to the spring 35 is provided in the top of the window so that the operator has to manipulate only the single spring 35 at the bottom. With the window in the position at B in Fig. 3, the box 45 is turned around so that the locking slot 47 is at right angles to the position shown in Figs. 3 and 5, it then being possible to niove the slide 32,- pulling the slide pivot pin 31 out of the locking slot 47 which in that position has its long direction parallel to the slot in the guide 33. The slide 32 can then be moved over to the position shown at C in Fig. 3, the window moving over into the position shown at D in Fig. 3, the brace portion 41 of the swing.- ing arm 40 assuming. the position E shown in that figure, and serving as a brace to hold the window in the position 1). With the window in the position D it is possible to gain access to what is the outer side of the window when closed, so that with the sash in this position it is possible to clean this outer side from the inside of the window.

When it is desired to return the window to its original position the inner end of the sash is pushed to the left as shown in Fig. 3, the window being moved in the position B, the catch pin 37 snapping into the hole in the guide 33 automatically so that the parts are locked in the operating position, or in the position shown in Figs. 1, 2, 3 and at.
